FLYWHEELS...yay or nay?

[08scion]

Are Flywheels really worth the money? What all can I expect to get from a performance light weight fly wheel and is it really worth the cash? What would be a better use of my money: A light weight flywheel or a Short shift?

[Redneck4csa]

They are worth the money. However, I would not see spending that kind of money on the part and install until you need a new clutch. I would go with a short shifter first.

[navylife59]

Or a LW crank pulley.

[Nathanr.6168]

yea... i should of had them put in better parts when i did my new clutch...

[08scion]

okay, so what your telling me is if i were to get a new flywheel i'll need a new clutch or light weight crank pulley? why is that? How much difference in performance will i see with a new clutch? a new LW crank pulley? what kind of performance change will i see?

[Redneck4csa]

No, you don't NEED to get a new clutch or pulley if you buy the flywheel. I'm just saying that it would be more cost effective to wait until you need to get a new clutch so that when they have the clutch out, they can replace the flywheel as well. Unless you plan on doing the install yourself. A lightweight crank pulley can be installed at any time. You should see a small but noticeable increase in power over the entire RPM range. Lightweight crank pulleys will reduce the rotational mass of the engine, thus letting it spin more freely. The same thing can be said for the flywheel. If you're not worried about money, go ahead and change the flywheel and crank pulley. If you're alittle money conservative right now, I would advise waiting until you need a new clutch to replace the flywheel.

a lightweight flywheel is like the best part ever haha. You actually feel a difference on the butt dyno. As for putting a new flywheel, you mightaswell wait till you get a new clutch because of the cost of installing it. Unless you wanna do it yourself.

As for the lightweight crank pulley, although there is alot of controversy, its a pretty good mod that I use on my daily drivers. way cheaper mod and something you can install yourself.

You will see quicker revs and acceleration. A flywheel is of course, a really trusted and favorable mod over the crank pulley.

[Nathanr.6168]

any 1 know a good lightweight crank pulley? about how much of a cost are we looking at?

[cribbs-tC]

Nathan, from what I've read, you might want to be careful about getting a crank pulley. Probably the most "controversial" mod for the tC. After I did some research, I decided it wasn't worth it. I'd recommend you look into yourself as well ^_^

[Nathanr.6168]

yea, ive been reading about it since my post, dont think il be doing it, too many people saying its bad

[Redneck4csa]

A lightweight crank pulley shouldn't hurt anything. Just make sure it isn't underdriven...

[Nathanr.6168]

so same diameter and i should be ok?

[Redneck4csa]

Yes, sir. I would get one if I had the money. I have a couple of more important things right now though...Big plans coming up...

[Nathanr.6168]

Does anyone know of a good lightweight crank pulley?

Navy, whats your opinion on crank pulleys? Will they mess up my car?

[Redneck4csa]

Or a LW crank pulley.

He is the one that recommended it...

[cribbs-tC]

I've read some really bad stuff about any sort of aftermarket crank pulley on the tC. This is because the factor crank pulley is also a harmonic dampener, which helps prevent your engine from hitting that "exact" harmonic resonance that would cause terrible things to happen to the engine. The aftermarket crank pulleys lack this feature, thus making them not the safest thing in the world.

It's the ongoing argument about whether or not this is absolutely true that makes it a "controversial" mod.

[Mengsta]

harmonic dampener is just the rubber material that goes to the inside diameter of the pulley. This dampener is very important because it absorbs alot of vibration and keeps the engine balanced. You will definitely notice a tiny increase of engine noise and vibration, just as if u installed an engine torque damper.

Regardless of all the controversy, I honestly would have to admit I too have one installed. I read a book "four stroke performance tuning" published by hanes and written by professional engine builders /racers. I trust these guys over any BS written on forums. Basically stated is that a lightweight crank pulley should have no drastic side effects unless you drive your car extremely hard every single day. In an average low horsepower vehicle like ours, the change of drastic failure is very slim to non existant. Yeah, i noticed slightly more engine vibration, but my tc's engine is still smooth as hell during idle anyway. Better acceleration and pick up. I wouldnt say its such a big deal. A crank pulley is around 100 bucks. You either get it or you dont. Since I live in cali, a lightweight pulley is something that has nothing to do with CARB regulations and SMOG. So i just got it.

A good brand would be NST (Non Stop Tuning). hands down best service and quality. If you get a underdriven, you should notice a larger improvement, but you will need a new belt and its not recommended for drivers with high electrical consumption (a crazy sound system or a tv). I just chose to stick with stock diameter, more simple that way.

I don't have any hard number from a dyno, but I have an 06 Spec V, my friend has an 02 Spec, I have a few more things than he has done, I have cams and the ported tb and intake mani, but other than that, our mods are about the same, and I would pull 2 cars on him easy, granted the gearing in the 06 is a little different but not THAT much different. Anyways, when his clutch went out he went with the clutchmasters clutch/flywheel combo, and I can't even get a full car out on him now.

How much does the stock tC flyweel weigh?? The Spec comes in at 30lbs stock, and most aftermarket ones are 11-12lbs. This will definitely be the next mod I do.

Hope this helps some. Sorry if anything sounds retarded I'm tired

[08scion]

so can i get away with just getting a flywheel and no other mod to accompany it for a while...a long while and have no negative side effects... this is my daily driver so i need it to last a long time. Basically what im asking is if i just do the flywheel and nothing else, whats gona happen to my car... Good and bad.

[shawnm565]

I went with the LW flywheel first and im staying far away from the LW crankpully.
